FLUSH VALVE. APPLICATION FILED'JULY 13`i 1918.v

1,300,001, l Patented Apr. 8,1919.

g f Mmmm WITNESS end of the vane the wings 28, 29, thereof aie recessed as indicated at 31.

Associated with the parts hereinbefore described, I also employ a cup member 32. This is connected with a lever 33, and Vas illustrated, may be an integral part thereof. The lever 33 terminates in a rib 34 which is an integral extension on the under surface of the cu pr 32. The lever 33 is provided with a boss 35 adapted to bear against the face of the blade 25 and through the lever and boss and the blade 25, a pivot 36 is passed upon which the lever and the cup are adapted to swing. The lever 33 is so mounted that the free end thereof extends through the recess in the lower or inner ends of the wings 28, 29, of the vane 27, and the blade 29 is provided with a lug 37 against which one edge of the lever 33 is adapted to contact in the operation of the valve. Furthermore, it will be noted, that as clearly illustrated in Figs. 4 and 5, the lower end of the wing 28:

as indicated at 38 lies between the lower portion of the blade 25 and the lever 33 and is adapted to bear against Vthe boss 35 for a purpose which will be hereinafter explained.

The hereinbefore described apparatus may I be operated by any suitable mechanism, for

instance as illustrated in Fig. 1, by a lever 39 adapted at one end to engage in a slot in the overflow pipe 22 and pivotally mounted at 40 adjacent its opposite end in the bracket 41 secured to the tank 10. Secured to the opposite end of the lever 39 is one end of a pull-chain 42 and in suitably placed positions the overflow pipe may be provided with one or more apertures 43 through which when the water in the tank reaches the same, the water will overflow through this pipe.

The wing 29 as clearly illustrated in Fig. 4, may be provided with bosses 28 which when the vane is in the dotted position, prevent the wing 29 from contacting in its entire surface with theblade 26 so as to in sure the proper action of the vane by pre. venting its, adhesion to the blade 26 by any means whatsoever.

Inv the operation of this apparatus the parts of the valve normally assume the positions shown in Figs. 1, 4 and 5. While the e Avalve is held in its normally seated position against the upper edge of the tubular body portion 12 of the pipe itting, the parts of the valve arey held in this ,position vin the tubular body member by the'end 29 of the wing'28 bearing against the inner surface of the tubular body member 12. But when the valve is raised from its closed position, asshown in- Fig. 1, to its open position as shown inl Fig. 2, in which the Washer or valve 19 leaves its seat on the upper or outer end of thev tubular body member 12, the

water or other medium in the tank will be permitted to Vflow' through the tubular body membeizto the flush pipe 15 and the pressure of the water acting against the wing 29 forces the vane from the position shown in full lines Fig. 4, to that shown in dotted lines therein. In this action as will be understood, the cup 32 will also descend from the full line position, Fig. 4, to the dotted line position, this action being caused by the action of the water against the cup and being assured by the end 38 acting against the boss 35. In this position, the end 29 of the wing 28 extends beyond the upper end of the tubular body member 12, and so long as the pressure against the cup 32 and the wing 28 is suiiicient to maintain these parts in these positions, the valve will lremain open. After the pressure decreases, however, the vane 27 will gradually swing to the full line position as shown in Fig. 4, and in so doing, will gradually swing the lever 33 so as to raise the cup 32 by the action lor the lug 3 7 against the edges of the lever 33. In so doing as will now be understood, the water pressure against the cup is not only reduced but the water remaining in the cup, permitted to iow therefrom as the same is tilted. In this manner the sudden seating of the valve is prevented, and dependent upon the size and inclination of the cup, the pressure at which the valve is closed may be controlled within predetermined limits.

I claim as my invention:

1.. A Hush valve apparatus comprising a tubular body member having a seat thereon, a valve member adapted to bear against said seat, a vane inovably connected to said valve member, and a device also movably connected to said valve `member and coacting with said vane so that the pressure exerted against the vane and said device by a medium liowing lthrough said tubular body member causes a part, of said vane to bear against said tubular body mer'ber to maintain the valve in an open position.

2. A 'lush valve apparatus comprising a tubular body member having a seat thereon, a valve member adapted to bear against said seat, a vane pivotally connected to said valve member, and a device also pivotally connected to said valve member and coacting with the said vane so that the pressure exerted against the said device andy vane by a medium flowing through said tubular body member causes a part of the said vane to bear against the said tubular body member to maintain the valve in an open position.

3. A flush valve apparatus comprising a tubular body member having a seat thereon, a valve member adapted to bear against said seat, a vane movably connected to said valve member, and a cup member also movably connected to said valve member and coactin with said vane so that the pressure exerted against the vane and said cup member by a medium flowing through said tubular body member causes a part ofsaid vane to bear against said tubular body member to main-` seat, a vane pivotally connected to the said valve member, and a cup member also pivotally connected to said valve member and coacting with the said vanefso that the pressure exerted against thel said cup member and vane by a medium flowingthrough said tubular body memberfcauses a partL of the said vane to bear against the said tubular body member to maintain the valve in an open osition. n

5. iiush valve Aapparatus comprising a tubular body member having a seat at the end thereof, a valve adapted to bear against said seat, a plurali-ty of angularly placed blades movably `fitting within saidtubular body member and connected to the said valve, a vane pivotally connected to one of the said blades, and a device also pivotally connected to one of the said blades and associated and coacting with the saidvaneso that the pressure exerted against thesaid device and vane by `a medium iowing through the said body member causes a part of the said vane to Vbear against a portion .of the said tubular body member to maintain the valve in an open position.

`t. A flush valve apparatus comprising a tubular body member havinga seat" at the end thereof, a valve adapted to bear against saidseat, a plurality of angularly placed blades movably fitting within said ytubular body member and connected to the said valve, a vane pivotally connected to one of the said blades, and a cup member also pivotally connected to one of the said bladesv and associated and coacting with the said vane so that the pressure exerted against the said cup memberand vane by a medium flowing through the said body member causes a part ofthe .said vane to bear against a portion of the said 4tubular body member to maintain the valve in an open position.

7. A flush valve apparatus comprising a tubular body Amember having a seat at the end thereof, a valve adapted to bear against the said seat, a plurality of an gularly placed blades secured to the said valvefand fitting,`
